really? you mean if I took a .458 bullet mold, cast some lead bullets, gas checked the bullets, loaded them to 45/70 speeds that it would be expensive to shoot? you can buy a magazine fed 50 bmg upper, but 50 bmg is fucking useless.

if you cast your own bullets that is a diff story. but the OP has told us he does not reload and is stuck buying factory.

why is .50BMG useless? you could put a hog down at 2 miles with a .50 BMG
